IMPROVE!) eurer-AIN-IIXTIJRE` `'.ihe Schedule vreferred to in these I lett v -Be it known that I, GEORGE P. FULLER, of the city of Philadelphia, and State of Pennsylvania, have invented a new and improved" Mode of Hanging WindowShades iup: relation to ventilation; and I do hereby declare that the lfollowing is a full and exact "description thereof, 'reference .being `had to the acccmpanying drawings, and to the letters of' reference marked thereon.

The nature of my invention mainly consistslihthe arrangement of a pinion on ene' end' of the v rolleron v which thecurtain is wound, andl combining therewith a permanent rack, which is arranged on the rwindowfacing, to preserve the height of the lower end of the `curtain in the adjustment of the upper sashthe roller being supported by brackets, attached to the sash, and

moving with the same, so that the pinion, by Vbeing turned around 'as it runs down the rack, winds the curtain around the; roller, to leave an open `space above the sash for the free passage of air, without i altering the height of the lower end of' the shade.

It further consists in the arrangement of a revolving shaft above said pinion, which has a pinion or small gear-wheel on one end, and a' pulley on the other, which is also fast to the shaftand which is providedwith an endless cord, so that `when the upper sash is in its rnost elevated position, the two pinions shall gear into each other, and, by the `manipulation of the cord, saidrollerbe turned either way, as .may

be required, to vwind, 0r unwind the curtain or shade, for the adjustment of its lower end.

It also consists in the arrangement of a gum roller 'v on one or both of the brackets which sustain `the shade-roller, so asfto bear upon the window-jamb, as the sash is moved up and down to hold the same'in any adjusted position. v l

' rlhe invention will be understood by the following description.

.In the accompanying drawingsv Figure 1 is a front viewof a windo\v in. which the shade is hung on a roller, the journals of which have lbearings in the brackets F F, that are secured to the i i upper sash O.

Figure 2 is a vertical section air to pass eely over it, for-the more perfect ventif 'atlthe line a .bofy

day of May, 1869.

ers Patent and making part of the same lation of the room, and to prevent strong'currcnts flapping the shade, which is fincidentalto-the usual mode Vof retaining the upperend in its elevated position, I attaeh brackets F to the upper part of the sash C, for the support of the journals a a of the said roller E.

AAnd to preserve the requisite height to the lower end of the shade, there is a .spur-wheel, G, on one end of the' roller E, which vgears into the permanent rack H, on the Window-facing b.

' The wheel G, being at its pitch-line of the saine i diameter as the roller, as the shade is wound'around the latter, in the revolutions caused by the said wheel running down the rack H, the required height of the `lower end of the shade is preserved, with but a slight variation, caused by increasing the size ofthe roll in thewinding of the'shade. v When the sash O is in its most elevatedV position,

the wheel G is brought into gear with` the pinion l, on one end of the shfort shaft J, and there being a sheave, K,'ou the other end ofthe shaft, the height ofthe lower end ofthe shade isadj usted by means ofthe endless cord L, which passes around 'the sheave and the pin c.

The brackets F are more clearly in iig. 3. 1 A i The said rollers are constructed of vulcanized rubprovided with rollers, M, seen ber, or similar material, and readily yield to any ini equalities as the sash is moved up and down, and, by

'their friction and pressure upon the janib b', sustain tl1e.sas"h in any adjustedposition. v

The sashes may be sustained and locked by attaching a ilat spring provided with afriction-roller, to the lower end of the upper sash, so that the roller shall `bear against the outside of the lower sash, in the f 'movement up anddown of the. upper sash, and bc ,sprung upon the upper 'edge oi the lower sash when the former is brought inte its inost elevatcdposition.

What I claiin as my invention, and desire to secure by Letters Patent, is-

1. The combination and arrangement of the spnrwheel G, roller E, and rack H, with the sash C, for maintaining the proper height of the lower en d of the shade, substantially as described. v

2. The arrangement of the pinion I, sheave' K, shaft J, andeord L, in relation to the spur-wheel G, substantially as shown and specified.

` 3. The-arrangement of the guinlrollcrs M, on the brackets F, `substantially as described.

In testimony that the above is my invention, I have i hereunto set I ny hand and alved my seal, this 25th Witnesses STEPHEN Us'rIcK, WM. LARZELEEE.
